CY7C425-10JXCT

FIFOs Memory Overview

The CY7C425-10JXCT is a 1K x 9 asynchronous first-in first-out (FIFO) buffer memory. It features independent read and write operations at speeds up to 50 MHz with a maximum access time of 10 ns. The device utilizes dual-port RAM cells for true asynchronous operation and includes Full, Empty, and Half Full flags to prevent overrun and underrun conditions. It operates on a single 5V supply within the commercial temperature range of 0°C to +70°C.

FIFOs Memory Feature Summary

• Supports unlimited expansion in width, depth, or both via dedicated control pins
• Includes retransmit functionality for packet data transfer applications
• Provides TTL-compatible inputs and outputs

FIFOs Memory Applications

• Asynchronous data buffering between disparate clock domains
• Packet data transfer systems requiring retransmission capabilities
• Parallel interface expansion configurations

FIFOs Memory Procurement Notes

Verify the specific suffix JXC indicates a lead-free plastic leaded chip carrier package. Confirm the operating temperature range corresponds to the commercial grade specifications. Ensure compatibility with existing system voltage levels and timing requirements before integration.

FIFOs Memory Selection Notes

Select this component when a 1K x 9 word capacity is required for asynchronous FIFO applications. It is suitable for designs needing independent read/write clocks and flag-based flow control. Consider alternative speed grades if higher throughput is necessary.

FIFOs Memory Part Context

This part belongs to the CY7C4xx series of asynchronous FIFOs, which also includes capacities ranging from 256 to 4K words. The series shares common architectural features such as dual-port RAM cells and expansion logic, differing primarily in storage depth and access speed variations.

FIFOs Memory Replacement Considerations

Functionally equivalent parts include IDT7202, AM7202, and other CY7C425 variants with different speed grades or packages.
